This is a verrrry simple bot.
All it does is kill the Nastasia boss and loots her items. They are rare drops, and she hits like a truck so make sure to use a class than can hit and heal well.
UndeadSlayer is perfect for her, since she's undead. Alpha Omega may be a decent option B. (I'm still new to bots, so please give me feedback. If something doesn't work, give me a heads up and I'll do my best to fix it.)
Note: This event may not return, so farm for these items now. And any moderator may delete this thread as soon as the event leaves. I'll happily reupload it if I'm allowed and if this event comes back.
